2024-03-22 帮助5人

1、Gradle 4.x→7.4.1

6、PathVariable校验不通过默认返回500 =>修改为返回404错误

1、Gradle 4.x→7.4.1

1) 写法变更

complie 修改为 api

testcomplie 修改为 testImplementation

2)引入integrationTest 单测包

升级org.unbroken-dome.test-sets至4.0.0

3)修改Querydsl配置

增加配置：

compileQuerydsl {
    options.annotationProcessorPath = configurations.querydsl
}
configurations {
    querydsl.extendsFrom compileClasspath
}
querydsl {
    library = "com.querydsl:querydsl-apt"
    jpa = true
    querydslSourcesDir = "${buildDir}/generated/java"
}

4)修改apply plugin:java

apply plugin: 'java-library'

2、springBoot升级包修改

1)springcloud 同步升级至2021.0.3版本2)指定flyway 版本为7.15.0 8版本开始不再支持mysql5.7版本

3)client中引入包

api "org.springframework.cloud:spring-cloud-starter-loadbalancer"

4)移除spring-cloud-starter-netflix-ribbon引用与spring-cloud-starter-loadbalancer冲突

5)hystrix已弃用替换成spring官方推荐的 resilience4j 地址：https://github.com/resilience4j/resilience4j

5)指定commons-beanutils版本

6)指定commons-io版本

7)引入com.谷歌.guava:guava包(如果项目中有用到的话)

8)com.cosium.spring.data:spring-data-jpa-entity-graph版本升级至 2.6.1

9)querydsl-jpa版本升级至5.0.0

10)org.glassfish:javax.el版本升级至3.0.1-b12

11)commons-validator:commons-validator升级至1.7 老版本有安全漏洞

12)org.apache.commons:commons-collections4升级至4.4 老版本有安全漏洞

13)org.springframework.security.oauth:spring-security-oauth2 升级至2.5.2.RELEASE 老版本有安全漏洞

14) 使用PostConstruct注解需要增加引用

api "jakarta.annotation:jakarta.annotation-api:1.3.5"

15)增加推荐缓存 caffeine引用

com.github.ben-manes.caffeine:caffeine

3、代码修改

1) FallbackFactory类引用路径调整

2) @Email 注解类引用路径调整

3)APPLICATION_JSON_UTF8_VALUE 被弃用替换为APPLICATION_JSON_VALUE 新版会自动解析，不需要额外指定UTF-8字符集

4)@Nonnull注解修改为@NonNull

5)StringUtils 类需要修改为apache lang3包 spring中StringUtils中有多个方法过时

6)jodaTime在新版中已不再支持换成JSR-310 增加jackson-jsr310包在需要转换的Date类型字段增加@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate类型会自动转换

api "com.fasterxml.jackson.datatype:jackson-datatype-jsr310"

7)RequestMappingInfo原构造方法已过时替换成build构造

8)RabbitTemplate setReturnCallback已过时,替换成setReturnsCallback

9)JPA 对于有内部entity的jpa bean ，lazy注解不再生效会自动生成inner join语句，需要按业务修改

10)JPA 对于所有数据库操作都会默认开启事务，在配置项加上

enableDefaultTransactions=false

关闭jpa默认事务

11)jpa的更新与删除必须要开启事务，否则会报

No EntityManager with actual transaction available for current thread 错误

12)MongoDbFactory已过时，无法正常注入替换成MongoDatabaseFactory

13)配置taskExcutor线程池

@Configuration
public class AsyncConfig {

    @Bean
    public TaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        // 设置核心线程数
        executor.setCorePoolSize(20);
        // 设置最大线程数
        executor.setMaxPoolSize(50);
        // 允许核心线程超时
        executor.setAllowCoreThreadTimeOut(Boolean.TRUE);
        // 设置队列容量
        executor.setQueueCapacity(1000);
        // 设置线程活跃时间（秒）
        executor.setKeepAliveSeconds(60);
        // 设置默认线程名称
        executor.setThreadNamePrefix("cloud-async-");
        // 设置拒绝策略
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        // 等待所有任务结束后再关闭线程池
        executor.setWaitForTasksToCompleteOnShutdown(true);
        return executor;
    }
}

4、配置修改

1)spring.profiles配置已过时，修改为spring.config.active.on-profile

2)ribbon已弃用，要使用新的服务配置

spring:
  cloud:
    discovery:
      client:
        simple:
          instances:
             bizr-tradec-service:
               - uri: ${bizr.tradec.server.name:http://xxxx}
             globiz-service:
               - uri: ${globiz.server.name:http://xxxx}
             tendata-accounts-service:
               - uri: ${server.name:http://xxxx}
             wenda-service:
               - uri: ${wenda.server.name:http://xxxx}
             globalsou-company-service:
               - uri: https://xxx.com
             mailsou-service:
               - uri: http://xxx.com
             mex-service:
               - uri: ${mex.server.name:http://xxxx}
             mail-service:
               - uri: ${dmx-edm.server.name:http://xxxx}

3)后端服务间调用要去掉网关的前缀

4)当使用@PathVariable注解时，对于jpa可能查不到结果情况要加上required = false

5)有路径匹配配置增加配置参数

mvc:
  pathmatch:
    matching-strategy: ant_path_matcher

6)mysql驱动 com.mysql.jdbc.Driver 修改为 com.mysql.cj.jdbc.Driver

5、兼容zuul网关

1)指定spring-cloud-starter-netflix-zuul版本为 2.2.10.RELEASE

1)新加ZuulConfiguration文件

package cn.tendata.wenda.webapp.config;

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.boot.web.servlet.error.ErrorController;
import org.springframework.cglib.proxy.Callback;
import org.springframework.cglib.proxy.CallbackFilter;
import org.springframework.cglib.proxy.Enhancer;
import org.springframework.cglib.proxy.MethodInterceptor;
import org.springframework.cglib.proxy.MethodProxy;
import org.springframework.cglib.proxy.NoOp;
import org.springframework.cloud.netflix.zuul.filters.RouteLocator;
import org.springframework.cloud.netflix.zuul.web.ZuulController;
import org.springframework.cloud.netflix.zuul.web.ZuulHandlerMapping;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ZuulConfiguration {

    /**
     * The path returned by ErrorController.getErrorPath() with Spring Boot < 2.5 (and no longer
     * available on Spring Boot >= 2.5).
     */
    private static final String ERROR_PATH = "/error";
    private static final String METHOD = "lookupHandler";

    /**
     * Constructs a new bean post-processor for Zuul.
     *
     * @param routeLocator    the route locator.
     * @param zuulController  the Zuul controller.
     * @param errorController the error controller.
     * @return the new bean post-processor.
     */
    @Bean
    public ZuulPostProcessor zuulPostProcessor(@Autowired RouteLocator routeLocator,
            @Autowired ZuulController zuulController,
            @Autowired(required = false) ErrorController errorController) {
        return new ZuulPostProcessor(routeLocator, zuulController, errorController);
    }

    private enum LookupHandlerCallbackFilter implements CallbackFilter {
        INSTANCE;

        @Override
        public int accept(Method method) {
            if (METHOD.equals(method.getName())) {
                return 0;
            }
            return 1;
        }
    }

    private enum LookupHandlerMethodInterceptor implements MethodInterceptor {
        INSTANCE;

        @Override
        public Object intercept(Object target, Method method, Object[] args,
                MethodProxy methodProxy) throws Throwable {
            if (ERROR_PATH.equals(args[0])) {
                // by entering this branch we avoid the ZuulHandlerMapping.lookupHandler method to trigger the
                // NoSuchMethodError
                return null;
            }
            return methodProxy.invokeSuper(target, args);
        }
    }

    private static final class ZuulPostProcessor implements BeanPostProcessor {

        private final RouteLocator routeLocator;
        private final ZuulController zuulController;
        private final boolean hasErrorController;

        ZuulPostProcessor(RouteLocator routeLocator, ZuulController zuulController,
                ErrorController errorController) {
            this.routeLocator = routeLocator;
            this.zuulController = zuulController;
            this.hasErrorController = (errorController != null);
        }

        @Override
        public Object postProcessAfterInitialization(Object bean, String beanName)
                throws BeansException {
            if (hasErrorController && (bean instanceof ZuulHandlerMapping)) {
                Enhancer enhancer = new Enhancer();
                enhancer.setSuperclass(ZuulHandlerMapping.class);
                enhancer.setCallbackFilter(
                        LookupHandlerCallbackFilter.INSTANCE); // only for lookupHandler
                enhancer.setCallbacks(
                        new Callback[]{LookupHandlerMethodInterceptor.INSTANCE, NoOp.INSTANCE});
                Constructor<?> ctor = ZuulHandlerMapping.class.getConstructors()[0];
                return enhancer.create(ctor.getParameterTypes(),
                        new Object[]{routeLocator, zuulController});
            }
            return bean;
        }
    }
}

注意：使用zuul网关的项目无法使用spring-cloud-starter-loadbalancer，只能使用ribbon

在boot2.6使用ribbon时需要重写RibbonLoadBalancerClient类，并实现choose方法。

ServiceInstance choose(String serviceId, Request<T> request)

6、PathVariable校验不通过默认返回500 =>修改为返回404错误

@ControllerAdvice
public class GlobalControllerExceptionHandler extends ResponseEntityExceptionHandler {
/**
* PathVariable 校验不通过返回404错误
*/
protected ResponseEntity<Object> handleMissingPathVariable(MissingPathVariableException ex, HttpHeaders headers, HttpStatus status, WebRequest request) {
Map<String, Object> errorAttributes = new LinkedHashMap<>();
status = HttpStatus.NOT_FOUND;
errorAttributes.put("status", status.value());
return new ResponseEntity<>(errorAttributes, status);
}
}
